The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set with gentle heat, giving it a rich, smooth body.
- Lemon juice
- Adds acidity that brightens the sweetness and balances the richness of the yolks.
- Lemon rinds
- Provide aromatic lemon oils that give the custard its fragrance.
- Rich wine
- Adds body, flavor and sweetness to the custard base.
- Brandy
- Contributes aroma and warmth to the finished custard.
The step that matters
Stir over heat until thickened. Egg yolks thicken as they warm, but if the heat is too high they can scramble and turn grainy. Keep the heat gentle and stir constantly so the custard thickens smoothly.
Swap the lemon
How well each one fits the dish's main ingredients (egg, wine, brandy):
- Currantfits better
- Apricotfits better
- Grapefits better
- Lemonthe original
Fit is the average pairing score against egg, wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
